Spoon-leaved stonecrop: Drought tolerant perennial that can be used in hot, dry, sunny spot. ‘Cape Blanco’ has powder blue and white foliage which, between May and July, is topped by small flattish heads of yellow flowers. Though attractive in flower, the plants are at their very best in mid-winter when their colourful evergreen foliage and attractive shapes makes them very eye catching on a roof.
